Patent GB-1173565-A (GB)
Title: Colour Photography
Inventor: NEALE DENIS MANKTELOW
IPC: G03B27/73
Filed: 1966-07-21
Abstract: 1,173,565. Photographic colour printing. ILFORD Ltd. July 20, 1967 [July 21, 1966; Dec. 6, 1966], Nos. 32885/66 and 54585/66. Heading G2A. In a method of colour printing, the print material is exposed through the negative to light having at least two colour components controlled as regards either intensity or exposure time, such that printing is effected either with fixed colour correction or with colour correction in inverse proportion to the ratio of integrated transmissions to light of the said colours, fixed colour correction being used when said ratio departs by more than a predetermined proportion from a predetermined value, and in said inverse proportion when the ratio does not so depart. By "fixed colour correction" is meant that the ratios of the integrals against the time of the products of the light intensity incident on the negative and light attenuation be - tween negative and print material are in constant proportion. The method is of especial advantage in printing from negatives representing so-called "colour subject failures", i.e. representing a subject containing an abnormally high proportion of one colour. The colour printer itself may be basically of the known form shown in Fig.6, in which light from three lamps 1, 2, 3 passes through filters 11, 12, 13 of the three primary colours, and an integrating box 15, and projects an image of a negative 7 on to photo-sensitive print material 9. A proportion of the light is reflected into a box 17 containing a photo-cell which controls shutters 18, 19, 20 to terminate exposure to each of the three coloured lights. The usual exposure control circuit is modified by the addition of a time ratio controller, to provide required limitation of the ratios of printing exposure times for red, green, and blue light. Thus there is comprised, in addition to the integrator, voltage reference, voltage adder, and trigger circuit whose output is fed to an "OR" gate which controls the shutter Figs. 7 and 8 (not shown) the time ratio controller of Fig. 9 (not shown). This is responsive to the output of the trigger circuit in a first photo-electric control circuit corresponding to one of the three primary colours, and its output is connected as input to the "OR" gate of a second photo-electric control circuit corresponding to a second of the three primary colours. The time ratio controller produces, in response to a first and a second impulse, a third impulse which follows the second impulse at a time in controlled proportion to the time elapsing between the first and second impulses. Thus the exposure time of the two primary colours (e.g. red and green) is held to the required limitations as set out above.

Title: Radar signal recording and reproducing system
IPC: G01S1/02
Filed: 1967-11-30
Abstract: 1,207,330. Recording radar signals. JAPAN RADIO CO. Ltd. 30 Nov., 1967 [3 Feb., 1967], No. 54629/67. Heading H4D. The Specification describes apparatus for storing radar or sonar video signals on magnetic media and for reproducing said signals. A radar equipment 101 supplies video signals which are amplified at 102, trigger sync. pulses which are amplified at 103, and three scan bearing signals S1, S2, S3, one signal S2 being earthed, and the difference signals S13, S23 amplified at 105 and 106. The amplified video and trigger signals are combined at 104 and the combined signal recorded on track T1 of magnetic recording media 108. The amplified bearing signals are multiplexed at 107 and the resultant signal recorded on track T2 of the media 108. To reproduce the video signal, the combined signal on track T1 is read off and the video signal and trigger pulses separated at 109. The video signal is fed to a radar indicator 118 as are the trigger pulses after any necessary phase adjustment in regulator 112. The multiplexed bearing signals are read off and separated at 113. Demodulators 114 and 115, and remodulators 116 and 117, transform the bearing signals into signals applicable to the radar indicator. To allow for the trigger pulses being of opposite polarity to the video signal, a polarity matching device may be used after amplifiers 102 or 103. Range markers may be added to the combined video signal and height, range, time or audio (voice) signals may be added to the multiplexed bearing signal.

As shown the workpiece W is fed manually to grippers (24a), 24b on a carriage 22 for feeding it to a table 19 of a turret punch 18. Pivoted at 68 on the press frame 67 at the side of the press next to a transfer table 14 for moving a punched workpiece to a folding machine 39, is an arm 28 carrying the secondary gripper 26. Alternatively the gripper arm is mounted on a side table 20 movable to position the carriage along one axis. The carriage is movable relative to the table along an axis at right angles to the one axis. With the grippers (24a), 24b aligned with the gripper 26, the latter is actuated to grip the workpiece and then, by a pneumatic cylinder (70), Fig. 2 (not shown), to swing the arm about pivot 68 to move the workpiece on the transfer table 14. The table comprises a fixed frame 30 carrying bars 32 and a frame 31 carrying rubberized conveyer belts 35, tiltable about a pivot 37 into alignment with an inclined work support 33 of the folding machine 39. In the lowered position of frame 31 the belts 35 lie below the bars 32 so that a workpiece can be slid on to the bars but when the frame is raised the workpiece clings to the belts which move it up to gauging stops 40 on the support 33. The stops are movable towards the folding tools to position the workpiece. At the opposite side of the press there may be a shearing machine 50 to which punched workpieces are fed by a second pivoted gripper 26 which is mounted on a second movable table 20. The gripper may also be used to feed a workpiece into a shear 54 by moving the table 20. The shear has a table 55 with workpiece supporting balls 57 which are raised and lowered automatically by cam rods (59), Fig. 8 (not shown), actuated by movement of the gripper 26.

[Also in Divisions H3-H5] In seam welding metal sheets 8, the sheets which are flushed over the weld seam with protective gas from above and below, are held in position by individual electromagnets 11, 12 whose fields do not influence the arc 6 of a gas shielded plasma arc burner 22 and the arc is deflected into the centre of the surrounding protective gas envelope 9 by a magnetic field 5 oriented perpendicular to the arc 3 and to the welding direction. The field 5 is produced by coils wound around arcuate polepieces 2 (one only being shown in Fig. 1). Gas is supplied to the underside of the weld seam from a longitudinal channel 19 in welding support 13 which communicates with a dovetail grove 15 immediately below the weld seam via a hole 18 in support 13 and grooves 20, 21 in a non-conductive heat resistant bar 16 in groove 15. The protective gas is preferably a mixture of hydrogen and argon, the proportions of which are chosen to suit the thickness of the sheet. The sheets are urged into a common plane by rollers or shoes positioned in front of and behind the arc burner so that the sheets are not offset in the welding region. The arc nozzle 4 may be retracted. The annular protective gas nozzle 10 provides a conical gas envelope 9.

Abstract: 1,130,649. Filling bottles &c. HOLSTEIN & KAPPERT MASCHINENFABRIK PHOENIX G.m.b.H. 21 Dec., 1966 [29 Dec., 1965], No. 57108/66. Addition to 1,096,173. Heading B8T. A machine in accordance with Specification 1,096,173 is provided with a filling head 1 with a liquid chamber 2 fed from a liquid reservoir 50 by a pipe 6. A liquid valve 4 controls supply to a bottle 21 via a pipe 24 having radial bores 25; a gas passage 26 through the liquid valve, closable by a valve 27, connects the bottle interior with the space above the liquid in the chamber. The bottle interior may also connect via a float valve 20 and a rotary valve 19 with either a high or low pressure source provided by pipes 12 and 13 respectively, the former connected to the space above the liquid in the liquid reservoir 50, and the latter to a low pressure gas container 51. Valves 14 and 15 control the pressure applied to the bottle interior via the pipes 12 and 13 respectively. Operation of the various valves is effected by eccentrics 10, 28, 16 and 17 on a shaft 9 rotated externally. When a bottle is raised to the position shown, elements 22 on a vertically raised centering bell 23 open the rotary valve 19 and the bottle interior is connected to high pressure. The shaft 9 is turned and the liquid and gas valves 4 and 27 opened, and liquid falls into the bottle; gas displaced from the bottle flows through bores 25 to the chamber 2. Before the chamber empties, the high pressure valve 14 is closed and the valve 15 opened causing liquid to flow more quickly into the bottle, and fresh liquid from the reservoir passes into the chamber. Before the bottle is filled the valve 4 is gradually closed by the eccentric 10 whilst the valve 27 remains open, enabling liquid to flow through the passage 26 into the bottle until the bottle is overfull and the float valve 20 is closed. Valves 14 and 15 are now opened and closed respectively causing the excess liquid in the bottle to be returned to the chamber 2 via passage 26. Finally the valve 27 is closed by the eccentric 28.
